Accessing CORBA Services from Bluetooth Mobile Terminals

摘要

The recent development of mobile communications and mobile devices has created a demand for running distributed applications on mobile devices. CORBA is currently the most widely used middleware solution in fixed networks, providing an open, widely applicable and platform-independent technology that hides most of the complexity in distributed systems. However, CORBA is designed for fixed networks and is not suited for networks containing wireless links. The standardization body of CORBA has recently released a new standard for wireless access and terminal mobility in CORBA which provides a framework for the use of CORBA on wireless networks, and the mechanisms to hide mobility. However, it does not deal with what kind of wireless technologies and networks the suggested framework can be used for and what kind of requirements it sets for them. In this paper, we discuss these requirements, and propose ways in which the framework can be bridged together with a real wireless network technology, Bluetooth. This paper also presents the problems of Bluetooth from the viewpoint of wireless CORBA and suggests some possible solutions for them. This paper proposes, as a result, the architecture for the use of wireless CORBA over Bluetooth.
